Two BTM uplink of embodiment, downlink test
BTM downlink test refers to the test of the radiofrequency signal of the 27.095MHz emitted BTM antenna, in test
Hold includes energy and frequency.BTM uplink test refers to testing the centre frequency that vehicle-mounted BTM equipment receives transponder transmitting
For the radiofrequency signal of 4.23MHz, test content includes: message reception, decoding time, good code rate, the bit error rate, decoding number.Only
Have and the uplink and downlink of vehicle-mounted BTM equipment are all carried out testing just to calculate to have carried out complete survey to vehicle-mounted BTM equipment
Examination.It is may be implemented during departure from and returning to engine shed through the invention, the realization pair in the case where not changing equipment connection status
The uplink test and downlink test of locomotive.The present embodiment provides the tests of a kind of BTM uplink and downlink
Method, process are as follows:
1) detection locomotive drives into detection zone: locomotive vehicle-mounted BTM antenna real time emission transponder excitation letter during advancing
Number, trackside processing center passes through the pumping signal around receiving unit real-time detection.When locomotive proximity test region, at trackside
Reason center can detecte the variation of ambient energy by receiving unit, to know that locomotive drives into detection zone.
2) starting test: trackside processing center, which detects, executes following movement after locomotive drives into detection zone: 1. startings are surveyed
High module starts real-time measurement BTM antenna to the distance of receiving unit；2. the radiofrequency signal of real-time measurement BTM antenna transmitting；3.
Start RFID reader, prepares to read electronic tag, obtain locomotive information；4. controlling controlled loop wire to start to send message.
3) test b TM downlink: during locomotive passes through above receiving unit, trackside processing center passes through 27M
Signal receives the signal for acquiring the radiofrequency signal from the transmitting of BTM antenna in real time with processing unit, and recording BTM angel transmitting
Frequency and energy maximum value.
4) obtain locomotive information: when locomotive is close to RFID reader, trackside processing center passes through RFID reader reading
Locomotive information in electronic tag.Trackside processing center closes RFID reader after receiving locomotive information.Trackside processing center
The message that locomotive enters detection zone is sent to BTM detection service device, which can be pushed to data by BTM detection service device
Terminal.
5) and vehicle-mounted recorder platform establishes communication: after BTM detection service device gets locomotive information, inquiring the locomotive pair
Vehicle-mounted recorder platform ID is answered, to establish the data communication with vehicle-mounted recorder platform, starts the operation information for obtaining BTM.
6) test b TM uplink: when locomotive passes through the top of adjustable transmission unit, BTM can receive adjustable transmission
The message that unit is sent.All information when vehicle-mounted recorder platform will record locomotive by controlled loop wire at this time, including message,
Decode frame number, good code rate, the bit error rate, decoding time and working condition of each plate etc..Vehicle-mounted recorder platform believes these
Breath is sent to BTM detection service device.
7) data processing: after trackside processing center detects that locomotive is driven out to detection zone by receiving unit, at trackside
The message and energy information that the test information of BTM antenna and adjustable transmission unit emit can be sent to BTM detection clothes by reason center
Business device.BTM detection service device passes through data information and vehicle-mounted recorder platform of the comparative analysis from trackside processing center
Test of the information realization to BTM uplink and downlink.
Vehicle-mounted recorder platform of the invention has wireless communication ability, and after locomotive entering garage, BTM detection service device can be with
The ID of vehicle-mounted recorder platform is got by engine number, so that the data connection with vehicle-mounted recorder platform is established, thus real
The closed loop test of existing whole system.
Method for constituting closed loop test can also be with the following method: 1, as shown in figure 3, vehicle-mounted record logger is flat
Platform and trackside processing center directly establish data connection.Data connection is established with trackside processing center first after locomotive entering garage, it will
Data in vehicle-mounted recorder platform are sent to trackside processing center, to form the closed loop of entire test macro.2, such as Fig. 4 institute
Show, the closed loop of whole system is realized by manual dumping data.For not having the vehicle-mounted recorder of wireless data dump ability
Platform can be got on the bus by service personnel and carry out data dump, and the data of dump are imported data terminal and realize entire test system
The closed loop of system.3, as shown in figure 5, data terminal directly accesses existing BTM monitoring platform, (such as the BTM having been carried out is long-range
The system of monitoring) realize whole system closed loop.Data terminal is by accessing existing BTM remote supervision system, from existing
Operation information when locomotive passes through detection zone is obtained in system, realizes the closed loop test to whole system.For constituting closed loop
Test can also have the deformation of more other forms, improve, and should all be included in the protection scope of the present invention.
The test of the most weak response device of embodiment three
Currently, electricity business using the shaking transponder below BTM antenna and then observes BTM when testing BTM
The method of status indicator lamp.The distance of transponder distance BTM antenna can be constantly adjusted during the test, be only more than certain
When a distance (each Motor Car Institute standard is different), and vehicle-mounted BTM equipment can be decoded normally and just assert that BTM equipment passes through test,
Allow locomotive outbound.
The currently used method in scene has the following problems: needing two people to cooperate test, one is shaken response at vehicle bottom
Device, one is onboard seen lamp；BTM aerial radiation endangers maintenance personnel's health；It is measured between BTM antenna and transponder using ruler
Distance inaccuracy.
Can be automatically performed the test process through the invention, the message of the adjustable transmission unit transmitting of present invention the inside and
Energy, which can according to need, to be adjusted, and adjustment height bring is simulated by the adjustment to adjustable transmission unit emitted energy
Energy variation.
Compared to existing test method, the present invention is realized in departure from and returning to engine shed to the automatic test of BTM equipment.
After locomotive entering garage, service personnel does not have to step on car test survey one by one again, only need to can recognize the whole of BTM equipment by data terminal
A test process, only when detect equipment fault Shi Caixu step on vehicle investigation failure cause.
The above content is only the preferred embodiment of technical solution of the present invention, is not intended to limit protection model of the invention
It encloses.Any modification, equivalent substitution, improvement and etc. done within the spirit and principles of the present invention, should be included in the present invention
Protection scope within.
